1. T-34 (USSR)

First produced in 1940. Top speed: 34 mph. Range: 268 miles. The four-stroke 12-cylinder diesel engine gives a power-to-weight ratio of 15.87 horsepower per ton. Armor thickness: 65 millimeters Primary armament: 76.2-mm gun.

The T-34 scores near to full points for firepower, mobility and protection. It surpasses any other tank for ease of manufacture — gaining full points in the production category. The tank's fear factor would have been immense, and it was awarded just short of the maximum in that category.
